Davis connected against Jeremy Hellickson (10-7) leading off the fifth inning. The drive landed on Eutaw Street beyond the 25-foot wall in right field and gave the Orioles a 4-2 lead.

Wei-Yin Chen (7-6) gave up two runs and six hits in seven innings to help Baltimore win for only the third time in nine games. The left-hander was backed by three double plays, two of which he started.

Darren O'Day worked a perfect eighth and gave up a leadoff single to Wil Myers in the ninth before Brian Matusz walked pinch-hitter James Loney. Tommy Hunter then got two straight outs, and with runners on the corners, Kelly Johnson was thrown out trying to steal second.
